 identify the customer with the ID read by the reader when the customer enters the store; 
 track movement of the customer in the store based on the images acquired by the camera and identify one or more commodities taken by the customer in the store; 
 acquire commodity data of each of the identified commodities; 
 after the customer has left the store, perform a settlement process for the commodities based on the acquired commodity data; and 
 control the display to display a list of the commodities before the customer leaves the store. 
   
     
     
         2 . The system according to  claim 1 , wherein
 the processor is configured to
 track the movement of the customer and determine whether the customer faces the display, and 
 control the display to display the list of the commodities when determining that the customer faces the display. 
   
     
     
         3 . The system according to  claim 2 , wherein
 the list includes a name of each commodity and a cancellation button for cancelling the commodity.   
     
     
         4 . The system according to  claim 3 , wherein
 the processor is configured to
 count a total number of cancellations made by the customer via the cancellation button, and 
 accept the cancellation only when the total number of cancellations is equal to or less than a threshold value. 
   
     
     
         5 . The system according to  claim 4 , wherein
 the processor is configured to control the display to display an error message when the total number of cancellations exceeds the threshold value.   
     
     
         6 . The system according to  claim 4 , wherein
 the processor is configured to control the display to display the total number of cancellations together with the list of the commodities.   
     
     
         7 . The system according to  claim 1 , further comprising:
 a plurality of sensors installed on commodity shelves in the store and detecting movement of commodities displayed on the shelves, wherein   the processor is configured to identify each commodity in response to a signal transmitted from one of the sensors that has detected the movement of the commodity.   
     
     
         8 . The system according to  claim 1 , wherein
 the reader is installed at an entrance gate of the store.   
     
     
         9 . The system according to  claim 1 , wherein
 the display is installed in a digital signage terminal in the store.   
     
     
         10 . The system according to  claim 1 , wherein
 the processor is configured to identify the customer based on the image acquired by the camera.   
     
     
         11 . A method for processing commodity data, the method comprising:
 reading by a reader an ID of a customer who enters a store;   identifying the customer with the ID read by the reader;   tracking movement of the customer in the store based on images acquired by a camera and identifying one or more commodities taken by the customer in the store;   acquiring commodity data of each of the identified commodities; and   after the customer has left the store, performing a settlement process for the commodities based on the acquired commodity data, wherein   the method further comprises displaying on a display a list of the commodities before the customer leaves the store.   
     
     
         12 . The method according to  claim 11 , further comprising:
 determining whether the customer faces the display based on the movement of the customer, and   displaying on the display the list of the commodities when determining that the customer faces the display.   
     
     
         13 . The method according to  claim 11 , wherein
 the list includes a name of each commodity and a cancellation button for cancelling the commodity.   
     
     
         14 . The method according to  claim 13 , further comprising:
 counting a total number of cancellations made by the customer via the cancellation button, and   accepting the cancellation only when the total number of cancellations is equal to or less than a threshold value.   
     
     
         15 . The method according to  claim 14 , further comprising:
 displaying on the display an error message when the total number of cancellations exceeds the threshold value.   
     
     
         16 . The method according to  claim 14 , further comprising:
 displaying on the display the total number of cancellations together with the list of the commodities.   
     
     
         17 . The method according to  claim 11 , further comprising:
 detecting movement of commodities by a plurality of sensors installed on commodity shelves in the store, wherein   each commodity is identified in response to a signal transmitted from one of the sensors that has detected the movement of the commodity.   
     
     
         18 . The method according to  claim 11 , wherein
 the reader is installed at an entrance gate of the store.   
     
     
         19 . The method according to  claim 11 , wherein
 the display is installed in a digital signage terminal in the store.
